如何用C语言结构定义转换成Java code？ [英] How to convert C language structure definition into Java code?

问题描述

我的工作 ITLSSPProc.dll 有本地方法，它在C语言下面的结构定义，但我必须用Java编写code。我不断搜索的最后三天，但无法找到一个解决方案。

  1.typedef结构{
            无符号__int64 FixedKey;对于固定主机密钥// 8字节数
            无符号__int64 EncryptKey;对于可变密钥// 8字节数
            } SSP_FULL_KEY;            2.typedef结构{
            无符号__int64发生器;
            无符号__int64模量;
            无符号__int64 HostInter;
            无符号__int64 HostRandom;
            无符号__int64 SlaveInterKey;
            无符号__int64 SlaveRandom;
            无符号__int64 KeyHost;
            无符号__int64 KeySlave;
            } SSP_KEYS            3.typedef结构{
            SSP_FULL_KEY关键; //全键
            无符号长波特率; //包的波特率
            无符号长超时; //多久毫秒等待从站的应答
            unsigned char型会将PortNumber; //主机的串行COM端口号
            unsigned char型SSPAddress; //从站的SSP地址
            unsigned char型RetryLevel; //多少次尝试，从不答复
            unsigned char型EncryptionStatus; //这是一个加密的命令0  - 无，1  - 是的
            unsigned char型CommandDataLength; //在命令字节数
            unsigned char型CommandData [255]; //包含命令字节数组
            unsigned char型ResponseStatus; //响应状态（PORT_STATUS枚举）
            unsigned char型ResponseDataLength; //多少响应中的字节
            unsigned char型ResponseData [255]; //响应数据的阵列
            unsigned char型IgnoreError; //标志燮preSS错误框（0  - 显示，1燮preSS）
            } SSP_COMMAND
 

下面是Java code我都试过了，但我不能够调用本地方法：

 公共类SSP_FULL_KEY
                {
                    长FixedKey;
                    长EncryptKey;
                    公共SSP_FULL_KEY（长固定，长ENCR）
                    {
                        FixedKey =修复;
                        EncryptKey = ENCR;
                    }
            }        公共类SSP_COMMAND
            {
                //字符串会将PortNumber;
                SSP_FULL_KEY关键;
                长波特率; //包的波特率
                长超时; //多久毫秒等待从站的应答
                字符串会将PortNumber; //主机的串行COM端口号
                串SSPAddress; //从站的SSP地址
                串RetryLevel; //多少次尝试，从不答复
                串EncryptionStatus; //这是一个加密的命令0  - 无，1  - 是的
                串CommandDataLength; //在命令字节数
                的String [] = CommandData新的String [255]; //包含命令字节数组
                串ResponseStatus; //响应状态（PORT_STATUS枚举）
                串ResponseDataLength; //多少响应中的字节
                字符串ResponseData [] =新的String [255]; //响应数据的阵列
                串IgnoreError; //标志燮preSS错误框（0  - 显示，1  -  SUP preSS）                公共SSP_COMMAND（字符串COMPORT）
                {
                    波特率= 9600;
                    超时= 500;
                    =会将PortNumber COMPORT;
                    RetryLevel =5;
                    IgnoreError =0;
                    EncryptionStatus =0;
                    ResponseStatus =0;
                    ResponseDataLength =0;
                    SSPAddress =0;
                    CommandDataLength =0;
                    关键=新SSP_FULL_KEY（012345670123，012345670123）;                }
            }本地方法：OpenSSPComPort（SSPCO​​MMAND * CMD）
 

下面我传递的参数：

 指向SSP_COMMAND结构
    返回：
    WORD 0失败，1表示成功
 

和得到错误不合适的链接错误

I am working on ITLSSPProc.dll which has native methods, it has the following struct definition in C-language but I have to write code in Java. I have searched continuously for the last three days but can't find a solution.

1.typedef struct{
            unsigned __int64 FixedKey; // 8 byte number for fixed host key
            unsigned __int64 EncryptKey; // 8 Byte number for variable key
            }SSP_FULL_KEY;

            2.typedef struct{
            unsigned __int64 Generator;
            unsigned __int64 Modulus;
            unsigned __int64 HostInter;
            unsigned __int64 HostRandom;
            unsigned __int64 SlaveInterKey;
            unsigned __int64 SlaveRandom;
            unsigned __int64 KeyHost;
            unsigned __int64 KeySlave;
            }SSP_KEYS

            3.typedef struct{
            SSP_FULL_KEY Key; // the full key
            unsigned long BaudRate; // baud rate of the packet
            unsigned long Timeout; // how long in ms to wait for a reply from the slave
            unsigned char PortNumber; // the serial com port number of the host
            unsigned char SSPAddress; // the SSP address of the slave
            unsigned char RetryLevel; // how many retries to the slave for non-response
            unsigned char EncryptionStatus; // is this an encrypted command 0 – No, 1 - Yes
            unsigned char CommandDataLength; // Number of bytes in the command
            unsigned char CommandData[255]; // Array containing the command bytes
            unsigned char ResponseStatus; // Response Status (PORT_STATUS enum)
            unsigned char ResponseDataLength; // how many bytes in the response
            unsigned char ResponseData[255]; // an array of response data
            unsigned char IgnoreError; // flag to suppress error box (0 – display,1 suppress)
            }SSP_COMMAND

Here is the Java code I have tried, but I am not able to call the native methods:

            public class SSP_FULL_KEY
                {
                    long FixedKey;
                    long EncryptKey;
                    public SSP_FULL_KEY(long fix, long encr)
                    {
                        FixedKey = fix;
                        EncryptKey = encr;
                    }
            }

        public class SSP_COMMAND
            {
                //string PortNumber; 
                SSP_FULL_KEY key;
                long BaudRate; // baud rate of the packet 
                long Timeout; // how long in ms to wait for a reply from the slave 
                String PortNumber; // the serial com port number of the host 
                String SSPAddress; // the SSP address of the slave 
                String RetryLevel; // how many retries to the slave for non-response 
                String EncryptionStatus; // is this an encrypted command 0 - No, 1 - Yes 
                String CommandDataLength; // Number of bytes in the command 
                String[] CommandData = new String[255]; // Array containing the command bytes 
                String ResponseStatus; // Response Status (PORT_STATUS enum) 
                String ResponseDataLength; // how many bytes in the response 
                String ResponseData[] = new String[255]; // an array of response data 
                String IgnoreError; // flag to suppress error box (0 - display,1- suppress) 

                public SSP_COMMAND(String comport)
                {
                    BaudRate = 9600;
                    Timeout = 500;
                    PortNumber =  comport;
                    RetryLevel = "5";
                    IgnoreError = "0";
                    EncryptionStatus = "0";
                    ResponseStatus = "0";
                    ResponseDataLength = "0";
                    SSPAddress = "0";
                    CommandDataLength = "0";
                    key = new SSP_FULL_KEY(012345670123, 012345670123);

                }
            } 



native method:OpenSSPComPort(SSPCOMMAND * cmd) 

Here I pass the parameters:

    Pointer to SSP_COMMAND structure
    Returns:
    WORD 0 for fail, 1 for success

and getting error unsatisfied link error
